Plz help me im so stuck

To find B you have two multiply eight and six together which will get you 48 you put 48 in the place of B in the equation And since the height is 10 you would put 10 in the place of the H in the equation so now what you have to solve is V=1/3(48•10) 48×10 is 480 then you divide 480 by 3 which will get you 160 then you multiply 160 by 2 since there are two shapes so your answer would be 320 cubic inches
